The crowd that piled into Nebius shares during last year’s 470% rally is now asking a tougher question: can the company convert its massive construction pipeline into a steady stream of cash? The stock closed Tuesday at €241.95, just 7% off its record high, and has added 216% since January. The market capitalisation has swelled past €53 billion. But behind the headline gains lies a delicate balancing act between breakneck expansion and financial discipline.
Nebius is committing between $20 billion and $25 billion to capital expenditure in 2026 alone — a sum that must rapidly translate into recurring revenue. Management is targeting a 40% adjusted EBITDA margin while simultaneously erecting new AI factories across Europe. The goal is to lock in vertical power capacity of four gigawatts by the end of the year, a threshold that would put the company among the continent’s largest dedicated infrastructure providers.
The order book provides a powerful cushion. A five-year agreement with Meta Platforms carries a total value of up to $27 billion, of which $12 billion is guaranteed capacity. An earlier pact with Microsoft is worth $17.4 billion, and could rise beyond $19 billion with add-on services. On top of those, Nvidia injected $2 billion into Nebius in March, securing early access to the Blackwell and Vera Rubin architectures. Nebius will begin deploying Vera Rubin chips from early 2027, with enhanced AI capabilities available to customers from the second half of 2026.
Should investors sell immediately? Or is it worth buying Nebius?
That physical moat is taking shape on the ground. In Finland, a 310-megawatt AI factory in Lappeenranta is due to go live in 2027, positioning it as one of the largest facilities in Europe. Simultaneously, Nebius is ploughing £1.7 billion into three Nvidia-powered sites in the UK. The company has also partnered with Weka to speed up model training and reduce latency — a crucial edge in a market where every millisecond counts.
Yet the speed of this buildout introduces real risk. The annualised 30-day volatility stands at nearly 100%, and the stock trades 111% above its 200-day moving average of €114.30. The RSI of 60.7 suggests the rally is not yet overheating, but the gap from the 50-day average of €186.83 implies a potential 30% drawdown if sentiment sours. Any delay in commissioning the Finnish plant, for instance, would jeopardise the 2026 revenue forecast of $3.0 billion to $3.4 billion, and undermine the longer-term target of $7 billion to $9 billion in recurring revenue by year-end.
Institutional backers seem undeterred. Leopold Aschenbrenner’s Situational Awareness LP disclosed a 5.6% stake in May, worth approximately $2.6 billion at current prices. That kind of anchor support helps Nebius maintain its premium valuation in a sector where capacity remains desperately short. The next major catalyst arrives in the second half of this year, when the first Blackwell Ultra instances come online. A sustained break above the 52-week high of €261.00 would confirm the next leg of the cycle. Until then, all eyes are on the construction crews in Finland, the UK, and beyond.
